Dear Sir/Madam,

    I'm one of your customer, I ordered a set of books on your website two weeks ago, but I didn't received it until yesterday. And much to my disappointment, the books were too poorly packed up that the cover of one book were torn. To make matters worse, it is not a complete set, as I found one book missed.

    I'm sorry to have received such poorly service, and I believe I have every right ask you to deal with this problem. I hope you either return my money back or deliver a new set of books to me. Beside, I'd like to be informed of the process of your deal with my complaint.

    I'm looking forward to your reply.

    In recent decades, social isolation has been recognized as a major risk to our health and long life. It's twice as bad for you as being overweight and nearly as bad as smoking. The rising number of people who say they are affected, across a wide range of ages, is shocking. In reality, you can suffer the ill effects of loneliness even if you are not socially isolated.

Comedian Robin Williams made a striking observation in 2014: "I used to think the worst thing in life was to end up all alone. It's not. The worst thing in life is to end up with people who make you feel all alone." Tracking large groups over time indicates that perceived（感知的）social isolation carries its own risk for morbidity（发病率）and mortality.

    The perception of isolation—from others of being in the social aspect-is not only a cause of unhappiness, it also signals danger. Fish have evolved to swim to the middle of their group when predators（捕食者）approach, mice housed in social isolation show sleep disruptions and reduced slow-wave sleep and prairie voles（田鼠）isolated from their partners then placed in an open field explore their surroundings less and concentrate on avoiding predators.

    These behaviours reflect an increased emphasis on self-preservation in the social aspect. For instance, fish on the edge of a school are more likely to be attacked by predators because they are easier to isolate and prey upon. Such observations reflect a more general principle that perceived social isolation in social animals activates neural（神经系统的）, neuroendocrine（神经内分泌的）and behavioural responses that promote short-term self-preservation. However, these responses bring a cost for long-term health and well-being.

    The range of harmful neural and behavioural effects of perceived isolation documented in adults include increased anxiety, hostility and social withdrawal; fragmented sleep and daytime tiredness; increased vascular resistance and changed gene expression and immunity; decreased impulse control; increased negativity and depressive symptoms; and increased age-related cognitive decline.

    Sadly, to date, attempts to reduce loneliness have met with limited success. A series of randomized controlled trials showed that they had only a small effect. Among the four types of interventions（介入）examined, talking therapy that focused on inappropriate thought processes had the largest impact. Social skills training, social support and increased opportunities for social contact were much less effective.

    "Mom, what is that?" asked my son. "The Bride of Chucky?"

    The old doll I was holding was pretty scary. Her glass eyes were especially horrible, closing when she stood upright and flying open when she lay flat. Once she had been loved, but she had been stored in an attic (阁楼) for decades, where the extremes of heat and cold can be hard on a girl's looks. Throw her in the waste bin? Maybe. But first, let's check eBay.

    I clicked, supplied the required information about condition, including defects (i.e., "Only a miracle could save this doll"), and uploaded its photos. I sold it for $5.

    The buyer was happy: "As described!" he wrote on my feedback page. "Super seller!" The doll found a home and, I hope, a new life. Maybe she was used to repair other dolls. Perhaps those strange eyes got fixed and once again can inspire a child's love. It's a win-win, if you ask me.

    I also sold lots of other stuff. None of them brought in a lot of money, though I have been surprised at the occasional bidding war, like, for example, the one over an old swimsuit that would have made Brigitte Bardot look bad. And some customers, let's face it, are strange. Recently I had a hard time convincing an Australian would-be buyer of an Irish souvenir bell that I don't shop internationally; it's just too much trouble. He could have flown to Ireland and bought his own bell for the price he was willing to pay. Another time, a buyer complained that the electric wire on an old radio was dirty. Really? Dirty? The wire was black. But I aim to please, so I offered a refund.

    So why bother with the dealing and small profits? Because I don't like abandoning the past. All these treasures once had stories. They meant something. But the people who gave them that meaning are gone, and I simply cannot rescue everything. I can't even sew. So I find it satisfying that a new owner, discovered via eBay, will continue the story in his or her own way.

    That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the 4Tirst-nighf, effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.

    Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved.

    The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university's Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants' brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.

    Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.

    A new study has found the amount of antibiotics(抗生素)given to farm animals is expected to increase by two-thirds over the next 15 years. Researchers are linking the growing dependence on the drugs to the increasing need for meat, milk and eggs. However, the drugs could quicken the development of antibiotic-resistant infections(感染). Such infections are already a major public, health concern in the United States.

    The World Health Organization notes when people stop living in poverty(贫困), the first thing they want to do is eat better, rather than earn more money. For most people, that means their diet should contain more meat. With the rapid development of Asia, people there are eating nearly four times as much meat, milk and other milk products as they did 50 year ago.

    To meet the need, farmers have put many animals into smaller spaces. As the animals are crowded together, the easiest way to deal with some of the problems of crowding is to give them antibiotics. It's clear that antibiotics help animals stay healthy in a crowded environment and grow faster. But bacteria can develop resistance to the drugs gradually.

    Nowadays, doctors find antibiotics that once worked against the infections no longer work. The bacteria have learned ways to fight against the drugs. The heavy use of antibiotics in animals is responsible for the growth of antibiotic resistance worldwide. In the United States, at least two million people get drug-resistant infections each year and at least 23,000 die from an infection.

    Europe has banned the use of antibiotics to increase animal growth. And the United States is hoping to persuade farmers to stop using antibiotics for that purpose.

    Josh Katz works at the New York Times. His common job is to use information to tell interesting stories. In December 2013, Katz built a quiz on the Times website. It asked people about the words they used to describe things and events. It also asked how they pronounced common words. The quiz then used people's answers to decide where in the United States they were from.

    The quiz got more than 350, 000 results. Katz turned the results into a book. In Speaking American, he studies regional differences in how Americans talk.

"A lot of people's language shows who they are and where they are from, in a very personal way", Katz said.

Katz says people are often surprised to learn that the way they talk can show where they grew up. Most Americans don't realize they use regionalisms — or words and phrases specific to a particular part of the country. But just about everyone does. Almost every major U.S. city has a few unique terms. For example, in Philadelphia, Pennsylvania, the night before Halloween is known as Mischief Night. Anyone who calls it that is likely to be connected to the city.

    Katz himself was surprised by how many common words are regional. "There are a lot of words I use that I just thought were standard words," he says. "Then I found out some of these words were actually a product of my upbringing."

    For example, he says, "I thought everyone said 'sneakers' (运动鞋) and not 'tennis shoes'." But it turns out "sneakers" is connected mostly to the Northeast. That's where Katz is from.

    Some scholars think that language in the U.S. is growing more homogeneous (同类的). But Katz disagrees. "These regional differences are here to stay." he says.

    Not only are people still using common regionalisms, but there are new ones appearing all the time, according to Katz. There's no way to predict how language will change in the future. But Katz sees more changes coming. "The only sure thing about language is that it's going to keep moving." he says.
